Trudeau last week said he would not accept new pro-life candidates in his party.

In response, Cardinal Thomas Collins said that party unity is important but "does not extend to matter of conscience and religious faith."

On Thursday Trudeau said his party welcomes anyone "regardless of personal views."

However, without explicitly saying he would whip the votes of his current caucus, Trudeau said that "when it comes to voting on legislation that would limit a woman's right to choose "¦ we vote to uphold the charter."

Canadians will soon find out if Trudeau will force his caucus to vote pro-abortion.

The NDP's Niki Ashton tabled a motion last week asking MPs to affirm if they believe "a women's right to choose abortion is a fundamental question of equality and human rights."
